In a statement Thursday, Sen. Tom Harkin (D-Iowa), chair of the Senate Health, Education, Labor & Pensions Committee, announced he intends to hold a hearing on ENDA on June 12.

“Every American deserves an equal opportunity to earn a good living, judged by their talent, ability and qualifications free from discrimination,” Harkin said. “Workplace discrimination based on an employee’s sexual orientation or gender identity is reprehensible and has no place in our nation.”

Harkin continued, “This upcoming HELP Committee hearing will provide an excellent opportunity to build on the Committee’s previous work and help advance our shared goal of equal rights for all Americans. I am hopeful that working together, we will reach a point where lesbian, gay, bisexual and transgender persons enjoy the same rights and protections, and full equality, as all our fellow Americans.”

According to the statement, further details about the hearing will made be public at a later time. Justine Sessions, a HELP committee spokesperson, said she doesn’t have information yet on witnesses.

The hearing could be the first opportunity for a transgender witness to testify before the Senate on LGBT workplace discrimination. In 2009, the committee held a hearing on ENDA, but no testimony came from a transgender witness. Thomas Perez, assistant attorney general for the Justice Department’s Civil Rights Division, testified on behalf of the Obama administration in favor of ENDA.

The announcement follows growing calls for a hearing on ENDA. In a letter dated May 9, Merkley, the lead sponsor of ENDA in the Senate, as well as co-sponsors Mark Kirk (R-Ill), Robert Casey (D-Pa.), and Susan Collins (R-Maine) call for the committee to hold a hearing.

“As strong supporters of this legislation, we urge you to schedule a time for Committee members to consider this proposed legislation,” the senators write. “ENDA embodies the American ideal of fairness: employees should be judged on their skills and abilities in the workplace, and not on their sexual orientation or gender identity.”

Joe Solmonese, president of the Human Rights Campaign, joined the senators in a statement calling for the hearing on the same day.

“What matters in the workplace is how you do your job but unfortunately no federal law bans workplace discrimination on the basis of sexual orientation or gender identity,” Solmonese said. “We encourage the Senate HELP Committee to schedule a hearing on this critical bill.”

The Washington Blade reported in March that LGBT advocates were pushing for a Senate hearing on ENDA as well as a markup of the legislation to move it to the Senate floor. All Democrats on the panel are co-sponsors of the bill — in addition as Kirk — so the committee would almost certainly be able to report out the legislation to the floor.
